Abstract:
A plot test was studied that the effect of mowing was on the root biomass and root system distribution of alfalfa and apricot,soil organic matter content,pH and electrical conductivity in the apricot garden.The results showed that the lateral roots of apricot tree were mainly concentrated in soil layer 20-60 cm.The distribution of alfalfa roots was gold tower type,and alfalfa roots were mainly distributed in more than 0 to 40 cm.Mowing had significant effects on alfalfa underground biomass,and with the times increasing of mowing,and the more times of mowing made that the distribution of alfalfa absorbing root was shallow.The more times of mowing effectively increased organic matter contents of the upper soil,but the effect of moving was not significantly on soil pH and electrical conductivity in the apricot garden.Therefore,suitable times of moving not only promoted the growth of underground part of alfalfa,and also could effectively improved the apricot garden soil nutrient status,but more times (more than 3 times) of moving increased more competition for nutrients between fruit trees roots and alfalfa roots.
